Listen Technologies LR-4200-072 Intelligent DSP RF Receiver | 72 MHz

The LR-4200-072 receiver brings intelligent DSP technology to professional assistive listening installations requiring dependable RF performance and extended runtime. Engineered with best-in-class RF sensitivity and 20dB lower noise floor than competing receivers, this unit serves boardrooms, lecture halls, courtrooms, and worship spaces where speech intelligibility cannot be compromised. The integrated neck loop and DSP loop driver optimize magnetic coupling for T-coil-equipped hearing aids, eliminating the need for external accessories that add cost and complexity to AV installations.

Advanced lithium-ion battery technology provides eight hours of continuous operation and recharges fully in 2.5 hours via standard micro USB connection. The OLED display presents channel assignment, volume level, and charge status at a glance, reducing support calls and venue staff intervention. Dual 3.5mm output jacks enable shared listening or connection to body-worn audio induction loops. Free iDSP software supports centralized programming, inventory tracking, and firmware management across receiver fleets. Field-replaceable battery design extends lifecycle and reduces total cost of ownership for integrators managing ADA compliance programs.

Operating across 72-76 MHz with 17 wideband and 40 narrowband channel options, this receiver pairs with Listen Technologies stationary transmitters for fixed installation or tour guide systems. Programmable squelch and automatic RF loss detection maintain connection integrity in challenging RF environments. The ultra-compact form factor simplifies dispensing workflows and storage in charging cases while meeting the ergonomic needs of extended-wear users.
